A splint joint (1) for a shaft comprising:
- a bushing receptacle (100) having a bushing receptacle body (110);
- said bushing receptacle (100) having a bushing receptacle body exterior (112), a bushing receptacle body tapered interior (114), a bushing receptacle top (116), a bushing receptacle bottom (118) distal from the said bushing receptacle top (116), a generally planar receptacle bushing mating surface (120) at the said bushing receptacle top (116), at least one bushing receptacle tapped hole (122) at the said bushing mating surface (120) penetrating the said bushing receptacle body (110);
- and
- a shaft (200) extending outwardly from and immovably affixed, by a drive shaft connection (230), to the said bushing receptacle bottom (118);
- said shaft (200) is in alignment with and concentrically sharing a bushing receptacle and shaft center line (140) extending from a bushing receptacle center (140) at the said bushing receptacle interior (130);
- and
- a bushing (300) having a bushing cap (320);
- the bushing cap (320) having a bushing cap top surface (326) and a bushing cap bottom surface (328);
- said bushing cap top surface (326) and said bushing cap bottom surface (328) are generally orthogonal to the said bushing receptacle and shaft center line (140);
- and
- at least one bushing cap machine bolt hole (322) penetrating the said bushing cap (320) and in alignment with the at least one bushing receptacle tapped hole (122);
- and
- at least one bushing cap push bolt tapped hole (324) extending from said bushing cap top surface (326) and through the said bushing cap bottom surface (328);
- the said at least one bushing cap push bolt tapped hole (324) is aligned to contact the said bushing mating surface (120);
- and
- a bushing drive shaft aperture (340) is sized to receive a shaft (200) and extends from said bushing cap top surface (326) through the said bushing cap bottom surface (328) and is concentrically aligned with the said bushing receptacle and shaft center line (140);
- and
- a bushing taper body (330) extends outwardly from the said bushing cap bottom surface (328);
- the bushing taper body (330) is sized to be slidably inserted into and extracted from the bushing receptacle body tapered interior (114);
- the bushing taper body (330) having a irremovably friction fit within the bushing receptacle body tapered interior (114);
- the bushing taper body (330) and the bushing receptacle body tapered interior (114) having generally the same tapered ratio;
- the said bushing taper body split (336) is narrow proximal the said bushing cap bottom surface (328) and is wider distal to the said bushing cap bottom surface (328);
- the said bushing taper body (330) has a spring function allowing the bushing taper body split (336) to close as the said bushing taper body (330) is inserted into the said bushing receptacle body tapered interior (114);
- and
- the said bushing cap bottom surface (328) is generally parallel to the said bushing receptacle mating surface (120);
- the at least one bushing cap machine bolt hole (322) is aligned with the said at least one bushing receptacle tapped hole (122) to receive machine screws and secure the said bushing receptacle (100) and the said bushing (300) from movement relative to the other during rotation;
- and
- the at least one bushing cap push bolt tapped hole (324) is positioned so that a threaded push bolt received by the at least one bushing cap push bolt threaded hole (324) will contact the bushing receptacle mating surface (120) and thereby urge the said bushing (300) away from and out of the said bushing receptacle (100) when the splint joint (1) disassembly is required.
